Data release notes

Voici un résumé des modifications :

Points clés à retenir :

• • La version 5.0 met à jour toutes les estimations relatives aux résidents mensuels et aux changements de résidence (données de janvier 2020 à aujourd’hui) en raison de l’utilisation de nouvelles données d’entrée
• • Les estimations pour juin 2025, qui faisaient auparavant défaut, sont désormais incluses dans la série chronologique
• • Une modification mineure a été apportée à la méthodologie d’estimation des résidents et des changements de résidence
• • Une partie de la terminologie utilisée sur la plateforme a été révisée

 

Mises à jour :

• • Nouvelles données d’entrée : la v5.0 utilise les agrégats CDR de tous les types d’événements (appels, SMS et désormais sessions de données mobiles), ce qui améliore la couverture de la population par rapport à la v4.0 et aux versions antérieures
• • Modification mineure du calcul des pondérations afin de mieux atténuer les variations importantes et de gérer les lacunes de données plus longues
• • Terminologie révisée : flux entrants totaux, flux sortants totaux, flux nets totaux, voyageurs, anomalie, expérimental, estimations.

Here's a summary of the changes:

Key take-aways:

• • V5.0 updates all estimates for monthly residents and relocations (data from January 2020 to now) due to the use of new input data

• • There is a minor change to the methodology to estimate residents and relocations
• • Some of the terminology used on the platform has been revised
  
  

Updates:

• • New input data: v5.0 uses CDR aggregates of all event types (calls, SMS and now mobile data sessions), improving coverage of the population compared with v4.0 and prior
• • Minor change to the calculation of weights to better attenuate large changes and handle longer data gaps
• • Revised terminology: total inflows, total outflows, total net flows, travellers, anomaly, experimental, estimates

v5.0 was released on 09 November 2026.

Here's a summary of the changes:

May 2026 - Key take-aways:

• • Further corrections to monthly estimates since November 2025 (after the data gap June-October 2025)

March 2026 - Key take-aways:

• • For the months June to October 2025, no CDR data are currently available, and no estimates are provided for that period. Residents estimates for November 2025 are calculated based on estimated relocations between May and November 2025. 
  
  

Key take-aways:

• • The country population total is now constant for the entire time series at 11,743,017
• • v4.0 is an overwrite of the entire dataset (data from January 2020 to now) due to two main corrections affecting the whole dataset
• • There are no changes to our methodology to estimate residents, relocations, presence and movements, and no additional sources for input data (only corrections). They remain the same as v3.0.
  
  

Corrections:

• • Calibration and corrections of baseline population estimates:
  •      • Calibration of baseline population estimates
  •      • Use of Microsoft building footprint for correction of two communal sections
• • Adjustments to take into account major network disruption from fuel crisis in October-December 2022, for the monthly resident and relocation statistics.
